Description
Technical field
Used borehole device when the utility model designs a kind of sand replacement method detection Subgrade Compaction, is mainly used in road
The Site Detection work of base compactness, belong to road construction monitoring field.
Background technology
In the work progress of road foundation, the detection to compactness is the important step in quality control, and compactness detects
If value is unqualified, it will largely influences the overall construction quality in road surface, and in a short time road surface will be gone out
There is the problems such as chicken-wire cracking and pit in existing structural destruction, road surfaces.
During subgrade construction at this stage, the detection to compactness generally all uses《Highway subgrade road surface scene is surveyed
Try code》(JTGE-2008) sand replacement method provided in carries out Field Compactness detection.So-called sand replacement method detects compactness, i.e.,
Soil sample after the completion of being compacted by the normal sand of known apparent density come isometric displacement, so as to which showing for soil sample be calculated
The actual dry density in field, and compared with the standard maximum dry density that laboratory test obtains, obtain actual compactness.
In actual mechanical process, due to lacking special supporting boring extracting soil equipment, mostly using manually digging hole.Manually
There is the problem of certain in borehole, on the one hand, the chisel tested pits, which takes, wastes time and energy, and at least needs two people's operations by turns；On the other hand,
The inwall that artificial chisel takes is sufficiently oily, also have impact on the accuracy of experimental result to a certain extent.
Utility model content
The purpose of this utility model is to provide a kind of borehole device for sand replacement method detection compactness, and its feature includes
Handle, nut, screw rod, guide cylinder, circular knife, pedal, cutting ring and bottom plate.Wherein, handle and affixed, spiral shell at the top of screw rod
Swing arm coordinates with nut, the affixed circular knife in screw rod lower end, guide cylinder crown center set connected nut, on guide cylinder lower end and cutting ring
Hold affixed, pedal is fixed in cutting ring upper end, there is designated depth mark on screw rod.
In actual mechanical process, the bottom plate of Special digging aperture apparatus provided by the utility model, which is first placed on, to be needed to detect
Road bed, by cylinder be aligned bottom plate mouth, the downward digging of rotational handle circular knife, is arrived while stepping on pedal by people
Reversely rotate handle after up to designated depth, soil sample is carried over ground into guide cylinder therewith, lower floor due to no soil, cutting ring to
Lower incision, the extracting apparatus after pedal contacts ground, soil is poured on bottom plate, carries out experiment calculation after collection.
It is round and smooth that can be designed so that of cutting ring digs the inwall of testing pits taken, so as to improve the precision of testing inspection.
Circular knife can be designed so that equipment without under big external force effect, reaching as big as possible to the interior soil body of testing pits
Disturbance destroy so that whole borehole process is time saving and energy saving.
The utility model has the advantages that：Simple in construction, reasonable in design, operating efficiency is high, easy to operate, pore-forming
Quality is good, and testing result accurately and reliably, can be saved effectively the integrated operation time.
Brief description of the drawings
Fig. 1 is stereogram of the present utility model；
Fig. 2 is Fig. 1 top view；
Fig. 3 is Fig. 1 sectional view.
In figure：1 is handle, and 2 be nut, and 3 be screw rod, and 4 be guide cylinder, and 5 be circular knife, and 6 be pedal, and 7 be ring
Knife, 8 be bottom plate.
Embodiment
In Fig. 1 and Fig. 2, device includes handle 1, nut 2, screw rod 3, guide cylinder 4, circular knife 5, pedal 6, cutting ring
7th, bottom plate 8.Handle is with affixed at the top of screw rod, and screw rod coordinates with nut, the affixed circular knife in screw rod lower end, at the top of guide cylinder
Intermediate sleeve connected nut, guide cylinder lower end and cutting ring upper end are affixed, and pedal is fixed in cutting ring upper end, and there is a circle at bottom plate center
Hole, its diameter are slightly larger than cutting ring overall diameter.
When carrying out sand replacement method detection compactness sampling, this instrument is in place, and operating personnel's bi-pedal is in both sides pedal
On, rotary handle of bending, circular knife is rotated downward by screw rod, reversely rotates handle after rotating to designated depth, soil sample with
Screw rod takes ground out of, is brought into guide cylinder, and after the lower section soil body is excavated, cutting ring is to incision soil, and cutting ring is completely into soil
When stop, both feet leave pedal, the lift-off of this instrument, collect the soil sample of residual in bottom plate, circular knife and hole, sand replacement method detects
Compactness borehole sampling work can be completed.During experiment, the base for filling sand cylinder need to be directed at drilled through hole location,
Soil layer is harder when being difficult to dig, can use longer steel pipe socket in handle, enlarging moment, in order to which circular knife is easier to pierce soil layer
In.
